This map uses high-contrast vector lines (sharp crimson and gold overlays) inspired by Expressionism. The vivid, harsh lines convey the hidden stress, kinetic shear, and sudden energy release along the seismic fault zones of Cagayan Valley.
Derivatives measure exact rates of change during seismic events. Logarithmic functions model wave attenuation as energy decays over distance:
$$\frac{d}{dx}[\ln(x)] = \frac{1}{x}$$
Calculus models ground acceleration rates, enabling structural engineers to establish retrofitting thresholds for critical public infrastructure.

Mga Paghahanda: Alamin ang Duck, Cover, and Hold. Maghanda ng Go-Bag at tiyaking nakatali nang maayos ang mabibigat na kasangkapan sa tahanan.
Pagninilay: Gagamitin natin ang ating isip upang maunawaan ang mga siyentipikong katotohanan ng sakuna, at gagamitin ang ating kilos-loob upang gumawa ng matalinong aksyon at maglingkod para sa kaligtasan ng ating komunidad.
